Title: Signal-powered frequency-dividing transponder
Inventor: CHARLOT LINCOLN H JR
IPC: G01S13/79
Filed: 1996-03-27
Granted: 2000-01-25
Abstract: A batteryless, portable frequency divider, such as used in presence detection systems for article surveillance or as used for article-location determination, includes a series LC resonant circuit connected directed across a parallel LC resonant circuit. One circuit is resonant at a first frequency and the other circuit is resonant at a second frequency that is a plural-integer-divided quotient of the first frequency. In one class of embodiments, either or both of the series and parallel resonant circuits includes a variable capacitance element, such as a varactor, in which the capacitance varies in accordance with the voltage across the variable capacitance element. The variation of the capacitance of the variable capacitance element in response to variations in energy in the higher-frequency resonant circuit resulting from receipt electromagnetic radiation at the first frequency causes the lower-frequency resonant circuit to transmit electromagnetic radiation at the second frequency. In another class of embodiments, the parallel circuit is resonant at the higher first frequency and the series circuit is resonant at the frequency-divided second frequency; the frequency divider includes a three-terminal semiconductor switching device having a control terminal, a reference terminal, and a controlled terminal, which is connected directly across both resonant circuits and between the inductance and the capacitance of the series resonant circuit and which switches on and off in response to variations in energy in the parallel resonant circuit resulting from the parallel resonant circuit receiving electromagnetic radiation at the first frequency to cause the series resonant circuit to transmit electromagnetic radiation at the second frequency.

Abstract: A trigger having a pawl operates a nozzle valve via a valve stem in a nozzle barrel bore. A spring in the barrel bore normally biases the valve closed. A toothed ratchet lever is pivotally resiliently secured to a trigger guard which protects the trigger from accidental activation. A ratchet tooth in an array of teeth on the lever engages the pawl to hold the trigger in a selected spray position of the valve, the teeth being normally biased disengaged by a second spring. The teeth each have a sharp crest which digs into the trigger in response to the spring bias on the valve stem overcoming the disengagement bias on the ratchet from the second spring. The nozzle is closed by squeezing the trigger to release the ratchet and pawl engagment such that the ratchet lever is pivoted to a disengement position by the second spring. The assembly comprises metal components in contact with hot fluid but which are thermally insulated with an outer casing spaced from the components by an air gap.

Title: Method for automatically pressing a filter into a blood-collection tube
Inventor: SARSTEDT WALTER
IPC: G01N1/34
Filed: 1997-11-19
Granted: 2008-01-29
Abstract: A filter is pressed down in a collection tube holding separated blood as a lower solids mass and an upper liquid mass defining an interface with the lower mass. The filter has a sleeve fittable in the tube with a lower end of the sleeve covered by a membrane that fits snugly in the tube. A vertical level of an upper surface of the upper liquid mass in the tube is detected and a pusher is engaged with an upper end of the sleeve to push the filter downward in the tube. A vertical level of the interface is also detected. Downward pushing of the filter is stopped when either the upper end of the sleeve is at a predetermined spacing above the vertical level of the liquid upper surface or the membrane is at the vertical level of the interface. Thus two separate events can trigger stopping of the downward pushing: reaching the interface or reaching a certain fill level in the sleeve. Contamination of the upper liquid mass by over-insertion of the filter is prevented as well as contamination of the pusher and, possibly, the sample and the workplace by insertion of the filter past the point where the upper end of the sleeve reaches the level of the upper surface of the liquid mass.

Abstract: A system for processing credit card transactions is disclosed. Transaction data to be processed is sent by point of system terminal to a terminal node connected to a sophisticated communications network. The terminal node uses routing data contained in the transaction data to establish a connection to a verification service host. The connection is established while the terminal node concurrently continues to receive and then validate the transaction dat a. Overall transaction processing time is reduced because the network connectio n needed for verification of the transaction data is established while, rather  than after, transaction data is received and validated.
